2. It is least expensive to use standard twin connection dampeners, save a "T" - use the other connection for the system drain, RV or gauge when not flowing through.

All Stainless Steel , With "Flexflon" PTFE
For LP Dosing Pump discharge, & suction of HP pumps where EPDM, Buna N, Hypalon, Fluoros, are NOT compatible. Twin connections are off the shelf inventory items. If you do not wish to intercept pressure pulsation, nor to flush before service, save the cost of an extra "T" and use the second connection for your RV. PI, or System Drain. For high pressure see PipeHugger HP.

The ratio of cross sectional areas inside the pipes for best pressure stability is 2:6:3:1. Where 2 is a suitable area for constant velocity suction supply, an area of 6 accommodates the peak velocity of the suction stroke. 3 will take the peak velocity of the discharge stroke, 1 will be ideal for the discharge.

Dampeners that do, flow goes through but pressure pulsation does not.

PulseGuard pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore our dampeners focus on the system related responsibility and are less related to pump liability.
